Severs is hanging 2-3 times in day

[praveen..]

Hi,
I have one HP ProLiant DL585 G1 Server and OS is Red Hat Enterprise Linux AS release 4 (Nahant Update 1).

Server is hanging if we execute any query on it.

Please find the attached file, it is the print screen to console.

Please let me know what should I do?

Thanks

Is it memory issue?

Praveen,

I have had a few issues like this, but this normally happens to me during boot/shutown. Thebest thing to do is to run yum/up2date and see if there are any patches available.
